Pls help I dont know how to do this

Answer:

1. CE = 63
2. x = 16

Step-by-step explanation:

Use proportions to solve.

Corresponding sides have same ratio.

<u>Question 1</u>

DE/EG = CE/EF

(6x + 3)/17 = (8x - 1)/21
21(6x + 3) = 17(8x - 1)
126x + 63 = 136x - 17
10x = 80
x = 8

CE = 8*8 - 1
CE = 63

<u>Question 2</u>

KM/MD = KZ/ZH

(x + 8)/21 = 32/28
x + 8 = 21*8/7
x + 8 = 24
x = 24 - 8
x = 16
